    Display Backlight - Keyboard Backlight

    Hi there,

    I have two problems under Hardy in a Macbook Pro C2D 2nd Generation.

    The first is that Ubuntu doesn't save the value of the display backlight so upon reboot it resets it to a default value. Is there any way I can programmatically set the display backlight upon boot in form of a session startup program? I tried macbook-backlight but it doesn't compile? Further I remember some time ago the gnome-power-manager application used to have some scrollbars to modify the display brightness(in AC and in Battery mode) but they don't exist now.

    The second problem I have is that after login when GNOME starts up, the keyboard backlight turns on and I have to press a button in the keyboard to turn it off. Is there any way I can turn it off by using a session start up program?

    Note that both brightness and keyboard backlight keys work perfectly under Hardy.

    Thanks for any help,

    I have managed to solve the first problem. Get the backlight sources from


    Both the source and the Makefile

    Edit the Makefile and adjust the



    LIBS=-lpci -lz

    and then run
    sudo make
    sudo make install

    When finishes, it will produce a backlight program stored in /usr/local/bin

    That's it

    a little help:

    backlight: read current value
    backlight value: write value [0-255]
    backlight +n: increase value by n
    backlight -n: decrease value by n

    You can the put it in the sessions start up so that it can load upon boot

    Now on to the second problem
